I got the map friend. I did not need to talk to Professor Oak, I just needed to talk to the man in Celadon and he gave me the map. Now I just need to wait for lapras time.
Thanks for all <3
I finished the kanto dex for the Mew mission, but prof oak, said that I only have 146 kanto pokemons .. I already have the 71 evolved pokemons, I do not know what to do.
